Multi-sheet article having removable portions comprising magnetized material

Abstract

A multi-sheet article comprising a plurality of sheets is disclosed. Each of the sheets has opposite first and second faces that share a common perimeter edge. Each sheet also has an edge margin that extends from a portion of the perimeter edge of the respective sheet. The edge margins of the sheets are bound to each other in a manner connecting the sheets to each other. At least a first one of the sheets comprises a first removable portion and at least one frangible connection that is configured and adapted to facilitate the separation of the first removable portion from the remainder of the first sheet and from the other sheets. This first removable portion comprises a portion of magnetized material. However, the edge margin of the first sheet of the multi-sheet article is devoid of magnetized material.
